SAFETY ATTACHMENT FOR INFANTS HlGiH CHAIRS.

SPECIFICATION formingpart of Letters Patent No. 661.764, dated November13, 1900.

Application filed March 14, 1900. Serial No. 8,582. (No modelil To allwhom it ma concern.

Be it known that I, HOWARD B. JOHNSTON, a citizen of the United Statesof America, residing at Brownsville, in the county of Fayette and Stateof Pennsylvania, have invented certain new and useful Improvements inSafety Attachments for Infants High Chairs, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in anattachment for high or baby chairs, and it is particularly adapted foruse to prevent the occupant from falling from the chair.

The object of the invention is to construct an attachment which can bearranged in a Vertical or horizontal position and is provided with anadjustable foot-rest.

Briefly described, the device consists of a pair of brackets which arepivotally secured at their upper ends to the seat of the chair and areeach provided with an oblong slot. A

foot-rest is adj ustably mounted in these slots, and a pair of links isprovided at each side of the chair for holding the brackets in aposition horizontal with the seat when so desired,

the especial construction of the elements entering into the combinationbeing fully described hereinafter.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification,and whereinlike numerals of reference indicate corresponding parts throughout theseveral views, in which Figure 1 is a side view of a high or baby chair,showing my improved attachment connected thereto in a vertical positionin full lines and a horizontal position in dotted lines. Fig. 2 is afront view of a high or baby chair, showing my improved attachmentconnected thereto and arranged in a vertical manner. Fig. 3 is adisassembled side view'of the supporting-hinge, partly broken away, asshown. Fig. 4 is a top plan view thereof, partly broken away. Fig". 5 isa perspective view of the supporting-hinge broken away at each end. Fig.6 is a perspective view of one end of the adjustable foot-rest.

Referring to the drawings by reference-nu merals, 1 indicates the backof the chair; 2, the side arms; 3, the legs; 4, the cross-brace; 5, theseat, and 6 a suitable tray connected to the top of the side arms in thedesired manner.

To the outer end of the seat 5 is pivotally secured to each sidethereof, as at 7, the bracket forming my improved attachment and whichconsists of the sides 8 9, each of which is provided with an elongatedslot 10 and are connected together at their lower ends by means of thecross-stri p 11. The reference-numeral 12 indicates a foot-rest providedat each end with a guide-lug 13, having a screw-threaded shank 14 formedintegral therewith. The lug operates within the slot 10, and the shankthereof carries a thumb-screw 15 to permit of vertically adjusting thefoot-rest 12, as well as to secure the same in position when properlyadjusted. To the inner corner of the lower end of each of the sides ofthe bracket is secured a link 16, as at 17, the upper end of this linkbeing provided with a slot 18. Pivotally secured to the front leg of thechair, as at 19, is a link 20, having the upper end thereof providedwith an L-shaped recess 21, in which operates a stop-lug 22, formedintegral with the upper end of the link 16. The link is further providedat its upper end with a headed stud or guide-pin 23. The two links 16 20form a supporting-hinge for securing the attachment in a horizontalposition, as shown in dotted lines of Fig. 1.

The hinge is operated as follows: Assuming that the same is in position,as shown in full lines inFig. l, the attachment is elevated to theposition shown in dotted lines until the stop-lug engages the upper wallof the recess in the link 20. The attachment at this point will be abovethe dotted lines shown in Fig. 1 when the attachment is lowered, forcingthe link 16 downwardly and the upper Wall thereof engaging the stud orpin 23, securely holding the attachment in position, as shown in Fig. 1in dotted lines. When it is desired 'to'lower the attachment, the sameis elevated until the lower wall of the opening of the link is engagedby the stud or pin 23. The attachment can then be lowered, for thereason that the stop-lug 22 will pass outwardly from the recess in thelink 21 and allow the links to assume the position shown in full linesof Fig. 1.

It is evident that the operation of the adjustable foot-rest can bereadily understood from the foregoing description.

It is thought the many advantages of my improved attachment for high orbaby chairs to prevent the occupant thereof from falling therefrom canbe readily understood from the foregoing description, taken inconnection with the accompanying drawings, and it Will be-noted thatvarious changes may be made in the details of construct-ion withoutdeparting from the general spirit of my invention.

Having thus fully described my invention, What I claim as new, anddesire to secure by Letters Patent, is-

l. The combination with a high or baby chair, of a bracket having itsupper end suitably connected thereto and carrying an adjustablefoot-rest, a link pivotally connected to said chair and provided with anL-shaped recess in its upper end, a headed stud or pin carried in theupper end of said link, a link pivotally connected to said bracket andprovided with an opening in its upper end having said stud or pinoperating therein, and a stop-lug formed integral with the upper end ofsaid last-named link and adapted to operv chair and each. provided withan oblong slot,

a foot-rest having a guide-lug on each end to engage and operate in saidoblong slots, a nut mounted on each of said guide-lugs for securing thefoot-rest in the desired position, a pair of links 20 pivotallyconnected to the legs of said chair and each provided near their upperends with an L-shaped recess, a headed stud carried in the upper ends ofsaid links, links 16 pivotally connected. at their lower ends to thebrackets and each provided near their upper ends with oblong slots toreceive said headed studs, and a stop-lug carried by each of said links16 and adapted to engage in the L-shaped recess of the links 20, allcombined and operating substantially as herein shown and described.

In testimony whereof I affix my signature in the presence of twowitnesses.

HOWARD B. JOHNSTON.
